Ok I know enough to be dangerous about heads. That being said please advise wisely. I have a 2000 M6 TA with about 400 HP. I have stock 243's on now. I have a 232/236 cam at .595 lift. I found a good deal on a set of 5.3L heads ported and everything. Should i buy that and put those on cheap? what kind of power will that make? Should I spend twice as much money and port my 243's? My goal is the 430-450 HP range. If the 5.3L heads will be a nice compliment to my cam i'm all for it but i do'nt know anything about 5.3L heads. My 243's have dual valve springs on so i figured i'm all set if i just switch them to the 5.3's as well.
